| 569 | ---help--- |
| 570 | The TAU supports an interrupt driven mode which causes an interrupt |
| 571 | whenever the temperature goes out of range. This is the fastest way |
| 572 | to get notified the temp has exceeded a range. With this option off, |
| 573 | a timer is used to re-check the temperature periodically. |
| 574 | |
| 575 | However, on some cpus it appears that the TAU interrupt hardware |
| 576 | is buggy and can cause a situation which would lead unexplained hard |
| 577 | lockups. |

| 588 | bound in /proc/cpuinfo. If the range is large, the temperature is |
| 589 | either changing a lot, or the TAU hardware is broken (likely on some |
| 590 | G4's). If the range is small (around 4 degrees), the temperature is |
| 591 | relatively stable. If you say Y here, a single temperature value, |
| 592 | halfway between the upper and lower bounds, will be reported in |
